Forget Asteroids: the Biggest Threat to Life on Earth Is Under Your Feet

A supervolcano is one of only two natural disasters with the capability of knocking out life on earth. While we have eyes trained skywards watching out for a planet-killing asteroid, a supervolcano can erupt without warning, and there is nothing that can be done to prevent that. It is believed that it was a supervolcano that accelerated the commencement of the last ice age and caused a genetic bottleneck on earth. Yellowstone National Park has one such supervolcano whose last eruption occurred 640,000 years ago. This video reveals some fun facts about supervolcanoes.

While none of the volcanoes that have erupted in recorded history have been supervolcanoes, they still caused immense devastation. Watch this footage of the explosion of Chile’s Calbuco volcano that caused the evacuation of 5,000 people.
